Vice President-elect Mike Pence is gearing up for a role in the Trump administration that will give him more clout than any of his predecessors ever had.

Donald Trump “has signaled repeatedly” that Pence “is going to be one of the most influential and powerful vice presidents in modern American history — and maybe American history,” Gary Bauer, a close Pence friend, told The Post.

“Trump sees himself as a public face of taking on draining of the swamp, but a lot of the day-to-day may end up in Pence’s portfolio.”

Pence will be working out of Trump Tower on the transition at least for the next few days, a source said.

The combination of the billionaire president and down-home Indiana governor may reshape conservatism for generations, said Bauer, an ex-GOP presidential candidate himself.

“We’re seeing the melding of Reagan conservatism, personified by Pence, with Reagan’s conservative populism, personified by Donald Trump,” he said.
